The change comes after the construction group failed to find a buyer for the division earlier this year.

Willmott Dixon said it would give Fortem more autonomy to target growth outside its core social housing market.

The business currently provides repairs and maintenance services to local authorities and housing associations across the country, employing a team of 1,400 engineers undertaking over 400,000 repairs each year.

It is currently responsible for repairs, maintenance and cyclical work on over 110,000 homes, working as a key partner for local authorities like Birmingham City Council and Rotherham Metropolitan Borough Council, plus housing associations like Midland Heart, Metropolitan, Orbit and Paragon.

To coincide with the new name, Willmott Dixon Partnerships’ sister company Willmott Dixon Energy Services, which insulates older homes, will be drawn into the Fortem brand to extend the services and skill-sets of the business.

Mike Williamson, managing director at Willmott Dixon Partnerships said: “As we focus on ensuring we support our existing clients in delivering the best service possible, the new name embodies our commitment to keep evolving as a successful business. We have strong ambitions for growth and this means that now is the right time to create a new stand-out brand to become recognised as a leader in property maintenance across all sectors, not just housing.”
